权限错误： [错误 13] 权限被拒绝： '/app/manage.py'

Question

我运行docker compose命令并获取"PermissionDenied"；错误大约两个月前，我使用了同样的代码，它运行得很好。我在互联网上搜索过，但解决方案帮不了什么忙。

docker-compose run --rm app sh -c "django-admin startproject app ."

它给了我一个错误：

Traceback (most recent call last):
File "/py/bin/django-admin", line 8, in <module>

PermissionError: [Errno 13] Permission denied: '/app/manage.py'

我的Dockerfile是：

FROM python:3.9-alpine3.13
LABEL maintainer="Kananappdeveloper"
ENV PYHTONUNBUFFERED 1
COPY ./requirements.txt /tmp/requirements.txt
COPY ./requirements.dev.txt /tmp/requirements.dev.txt
COPY ./app /app
WORKDIR /app
EXPOSE 8000
ARG DEV=false
RUN python -m venv /py && 
/py/bin/pip install --upgrade pip && 
/py/bin/pip install -r /tmp/requirements.txt && 
if [ $DEV = "true" ]; 
then /py/bin/pip install -r /tmp/requirements.dev.txt ; 
fi && 
rm -rf /tmp && 
adduser 
--disabled-password 
--no-create-home 
django-user
ENV PATH="/py/bin:$PATH"
USER django-user

我的操作系统是Ubuntu 22.04

提前谢谢。

使用命令ll检查文件夹app创建者的用户名。然后找出用户的用户id。

然后使用在Docker中创建具有该id的用户

adduser 
-u $ 
--disabled-password 
--no-create-home 
django-user

然后建造docker。
